CC   -!- FUNCTION: Part of the energy-coupling factor (ECF) transporter complex
CC       NikMNQO involved in nickel import. The complex confers nickel uptake
CC       upon expression in E.coli; can also transport cobalt with a very low
CC       affinity. {ECO:0000269|PubMed:16352848}.
CC   -!- SUBUNIT: Forms an energy-coupling factor (ECF) transporter complex
CC       composed of an ATP-binding protein (A component, NikO), a transmembrane
CC       protein (T component, NikQ) and a fused possible substrate-capture
CC       protein (S component, NikMN) of unknown stoichimetry. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the CbiQ family. {ECO:0000305}.
